[0002] In cleanroom environments of industries such as pharmaceuticals, medical devices, and electronics, sterilization and disinfection are core steps in ensuring production safety and product quality. Existing technologies, such as traditional high-pressure sterilization devices (e.g., the high-pressure sterilization device for hospital sterilization supply rooms with publication number CN210205405U), achieve high-temperature and high-pressure sterilization through components like hot air blowers and liquid pumps. However, their structure has the following limitations: Limited spraying range: Traditional spray pipes are mostly fixed or unidirectional swing designs, which make it difficult to cover the complex spatial structure of clean rooms, resulting in disinfection dead spots and uneven sterilization effect. At the same time, the unidirectional spraying mode requires an extended disinfection time to ensure coverage, which leads to increased clean room downtime and increased production costs.

[0003] Insufficient flexibility: The equipment is usually fixed and inconvenient to move, making it difficult to adapt to the dynamic disinfection needs of different areas in the clean room. In addition, the equipment occupies a large space, which affects production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a cleanroom sterilization and disinfection device. The spray pipe, driven by a reversible motor, oscillates back and forth, creating multi-angle spray coverage, thus improving sterilization efficiency compared to traditional devices. The movable component at the bottom of the liquid storage tank allows for flexible deployment, adapting to the dynamic disinfection needs of cleanrooms. Furthermore, the space occupied by the folded spray pipe is reduced, improving storage and transportation convenience. In addition, multi-directional spraying shortens the disinfection time per cycle, and combined with a low-power motor design, overall energy consumption is reduced. This device ensures efficient sterilization while also considering safety, environmental protection, and cost optimization, providing a reliable solution for cleanroom environment control in industries such as pharmaceuticals and medicine.

[0017] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0018] Please refer to Figures 1 to 8 As shown, an embodiment of the present invention provides a cleanroom sterilization and disinfection device, comprising: a liquid storage shell 1, a moving component 2 for moving the liquid storage shell 1 installed at the bottom of the liquid storage shell 1, a rotatable spraying component 3 installed on the side of the liquid storage shell 1, a rotary drive component 4 for driving the spraying component 3 to rotate installed at the top of the liquid storage shell 1 and corresponding to the position of the spraying component 3, and a limit support component 5 installed at the top of the liquid storage shell 1 and corresponding to the position of the rotary drive component 4. By adopting the above technical solution, the spray pipe 3013 reciprocates under the drive of the forward and reverse motor 401, forming multi-angle spray coverage, which improves the sterilization efficiency compared with traditional devices. The bottom moving component 2 of the liquid storage shell 1 supports flexible deployment of the equipment, adapts to the dynamic disinfection needs of cleanrooms, and the space occupied by the spray pipe 3013 is reduced after folding, improving the convenience of storage and transportation. In addition, multi-directional spraying shortens the single disinfection time, and combined with the low-power motor design, the overall energy consumption is reduced. While ensuring efficient sterilization, it also takes into account safety, environmental protection and cost optimization, providing a reliable solution for clean environment control in pharmaceutical, medical and other industries.

[0019] To facilitate convenient addition and uniform mixing of disinfectant, in this embodiment: a filling port 101 for adding disinfectant is installed on the top of the side of the storage tank 1, and a stirrer 102 for mixing the disinfectant inside the storage tank 1 is installed on the bottom of the side of the storage tank 1. The filling port 101 on the top of the side of the storage tank 1 facilitates rapid replenishment of disinfectant; the stirrer 102 installed at the bottom can stir the disinfectant in real time, avoiding differences in sterilization effect caused by uneven concentration, which is especially suitable for scenarios that require frequent replenishment or use of compound disinfectants.

[0020] To improve the mobility and stability of the equipment, in this embodiment: the moving component 2 includes a moving shell 201 fixedly connected to the bottom of the liquid storage shell 1. An electric cylinder 202 is fixedly connected to the center of the top of the inner wall of the moving shell 201. A lifting seat 203 is fixedly connected to the output end of the electric cylinder 202. Moving wheels 204 are fixedly connected to the four corners of the bottom of the lifting seat 203. The lifting seat 203 is driven to rise and fall by the electric cylinder 202, thereby realizing the extension and retraction control of the moving wheels 204. When movement is required, the moving wheels 204 descend to contact the ground for quick transfer; when stationary, the moving wheels 204 retract, and the liquid storage shell 1 directly contacts the ground, enhancing the stability of the equipment and preventing shaking during spraying.

[0021] To achieve efficient and multi-directional atomized spraying, in this embodiment: the spraying assembly 3 includes a pump 301 installed on the top side of the liquid storage tank 1. The side of the pump 301 is connected to the liquid storage tank 1 through an extraction pipe 3011. A delivery hose 3012 is installed on the top of the pump 301, and a spray pipe 3013 is installed on the top of the delivery hose 3012. Several atomizing nozzles 3014 are arranged at equal intervals on the spray pipe 3013. The pump 301 draws disinfectant from the liquid storage tank 1 through the extraction pipe 3011, delivers it to the spray pipe 3013 through the delivery hose 3012, and atomizes the disinfectant through the atomizing nozzles 3014, resulting in a wide coverage area and uniform spraying, significantly improving sterilization efficiency.

[0022] In order to drive the spray pipe 3013 to achieve reciprocating oscillating spraying, in this embodiment: the rotary drive assembly 4 includes a forward and reverse motor 401 fixedly connected to the top of the liquid storage shell 1. The output shaft of the forward and reverse motor 401 is fixedly connected to a drive turntable 4011 for driving the spray pipe 3013 to rotate. The forward and reverse motor 401 drives the drive turntable 4011 to rotate back and forth, thereby driving the spray pipe 3013 to oscillate within a set angle range, realizing multi-directional spraying and eliminating the dead angle problem of traditional fixed spraying.

[0023] To achieve folding storage and support for the spray pipe 3013, in this embodiment: a connecting rotating block 302 is fixedly connected to the end of the spray pipe 3013. The connecting rotating block 302 is rotatably mounted with a connecting rotating seat 3021 via a connecting shaft. The bottom of the connecting rotating seat 3021 is fixedly connected to the top of the drive turntable 4011. An L-shaped bracket 402 for supporting the spray pipe 3013 is also fixedly connected to the side of the drive turntable 4011 at the position corresponding to the spray pipe 3013. The end of the spray pipe 3013 is rotatably connected to the connecting rotating seat 3021 via the connecting rotating block 302, and can be folded to the top of the drive turntable 4011 in the non-working state, reducing space occupation. The L-shaped bracket 402 provides stable support during spraying, preventing the spray pipe 3013 from sagging due to gravity and causing the spray angle to shift.

[0024] To prevent residual liquid from dripping and contaminating the equipment when the spray pipe 3013 is folded, in this embodiment: a water collection tank 403 is installed on the top of the drive turntable 4011 and at the position corresponding to the spray pipe 3013. The water collection tank 403 on the top of the drive turntable 4011 can collect the residual disinfectant on the atomizing nozzle 3014 after the spray pipe 3013 is folded, preventing the liquid from dripping onto the equipment surface or the ground, and ensuring the cleanliness and safety of the equipment.

[0025] To enhance the stability and durability of the drive turntable 4011's rotation, in this embodiment: the limiting support assembly 5 includes a limiting rotating ring 501 fixedly connected to the bottom of the drive turntable 4011. A support rotating ring 5011 matching the limiting rotating ring 501 is installed on the top of the liquid storage shell 1 at a position corresponding to the limiting rotating ring 501. The top and sides of the support rotating ring 5011 are provided with several limiting balls 502 arranged at equal intervals. The support rotating ring 5011 is tactilely connected to the limiting rotating ring 501 through the limiting balls 502. The tactile connection between the limiting rotating ring 501 and the support rotating ring 5011 through the limiting balls 502 provides stable support for the drive turntable 4011, reduces rotational friction, and extends the service life of the equipment. It is especially suitable for cleanroom environments with high frequency and long-term operation.

[0026] The working principle of this utility model is as follows: Mobile and stationary switching: The electric cylinder 202 drives the lifting seat 203 to rise and fall, and controls the extension and retraction of the moving wheels 204, so as to realize the free switching between rapid movement and stable operation of the equipment.

[0027] Disinfectant solution is supplied evenly: The liquid inlet 101 works with the mixer 102 to ensure that the concentration of disinfectant solution is uniform. The pump 301 delivers the disinfectant solution to the spray pipe 3013 through the extraction pipe 3011 and the delivery hose 3012, and then sprays it evenly through the atomizing nozzle 3014.

[0028] Multi-directional spraying control: The forward and reverse motor 401 drives the drive turntable 4011 to rotate back and forth, causing the spray pipe 3013 to swing within a set angle range. Combined with the support of the L-shaped bracket 402, spraying without dead angles can be achieved. After spraying, the spray pipe 3013 can be folded to the top of the drive turntable 4011 to reduce space occupation.

[0029] Safety and stability assurance: The water receiving tank 403 collects residual droplets to avoid contamination; the limiting rotating ring 501 and the supporting rotating ring 5011 are connected by the limiting ball 502 to ensure the stable rotation of the drive turntable 4011 and extend the service life of the equipment.
